The question:

what is 2 divide by 2 1/8


The answer:

What is 2 divided by 2 1/8 ?


I’m going to compute the answer in two ways: 1) using decimals, and 2) using fractions


Dividing using decimals:

(2) ÷ (2 1/8)

Convert numbers to decimals

1/8 = 1 ÷ 8 = 0.125

2 1/8 = 2 + 1/8

= 2 + 0.125

= 2.125

Divide the two numbers:

(2) ÷ (2 1/8)

= 2 ÷ 2.125

= 0.941176


Dividing using fractions:

(2) ÷ (2 1/8)


Convert the mixed number 2 1/8 to an improper fraction

2 1/8 = 2 + 1/8

= 2*(8/8) + 1/8

= (16/8) + 1/8

= (16 + 1)/8

= 17/8


Divide the two numbers:

(2) ÷ (2 1/8)

= (2) ÷ (17/8)

= (2/1) ÷ (17/8)

Reverse the second fraction’s denominator and numerator, and then multiply the two fractions.

= (2/1) * (8/17)

Multiply the numerators and denominators of the two fractions

= (2*8)/(1*17)

= (16)/(17)

= 16/17



The final answer is:

decimal format: 0.941176
fraction format: 16/17





Thanks for writing.
